The system also does pretty well in the long tail. There's even a set of older (and some newer) games that run better than they do on modern versions of Windows - not a huge number, but not nothing and probably growing over time.

At this point, the largest problem left to solve is perhaps achieving pervasive support for anti-cheat middleware by multiplayer games, which requires vendor participation. A few have started collaborating, but there is more to do on this front.

There was just an article on the front page earlier today about 75% of the top 100 games on steam running on linux, with the remaining 25% mostly being due to anti-cheat software that isn't updated to support linux yet.

Protondb.com has a database to search for compatibility and if adjustments to command lines or a specific version of Proton are needed for getting games running.
